Funky DHTML effects from nested lists (as seen on gazingus and kryogenix) do not work. Looks like the DOM support isn’t quite there yet.

Some pages fail to display in a readable form at all—examples so far are SurfMind and bodytag.org (which continues loading infinitely—when I stopped it it had already downloaded over 3MB according to Opera’s status bar).

Javascript errors are accompanied by a popup window containing a back trace and extracts from the code that went wrong. Nice.

When it works, it’s fast.

A preview feature for small-screen browsing has been included—hit shift-F11 to see what a page would look like on an Opera small-screen enabled mobile device.

Verdict: Needs work—but then it’s a beta so that’s pretty much to be expected.
